technically, you could go by the BMI.. and "think" you wouldn't look right. But that's totally wrong.. if you follow those weights and such, you'll look fine.. but you can't go 260 your whole life, and then it say you need to be 160... without thinking you'll look weird...
but when you hit your BMI levels, your body is 100% top notch shape. That means hitting it with healthy eating, healthy exercise, everything... That takes a lot of hard work and skill.. but you'd look fine at the BMI levels and weights..
I've seen some big boys work at it for years, and perfect it.. it's about 2% body fat, and they are amazingly built..
It's a notch above a swimmers body.. it's very incredible to see in person, I'm not gay, but those BMI level people who go from being bigger to their size.. is just incredible with their dedication and such
